Adaptation to Turkish of the Self-Care of Heart Failure Index: A Validity and Reliability Study

Abstract

Introduction: Heart failure is a chronic and progressive disease with increasing prevalence and incidence worldwide, despite advances in science and technology, and it necessitates long-term follow-up, treatment, and care. Self-care in heart failure is one of the fundamental elements of quality of life and disability-free living. The aim of this study was to assess the validity and reliability of the Turkish version of the Self-Care of Heart Failure Index v.2 (SCHFI). Patients and Methods: The study sample included 233 patients who presented with a diagnosis of heart failure and volunteered to participate in the research at a training and research hospital. The data were collected using a personal information form and the SCHFI. The SCHFI was translated into Turkish, and the internal consistency coefficient and the item-total points reliability coefficient were analyzed for the reliability study. To determine structure validity, Explanatory Factor Analysis and Confirmatory Factor Analysis were performed. Results: The adaptation of the SCHFI to Turkish culture was found to have high structure validity and internal consistency in the reliability and validity studies. Conclusion: We concluded that the Self-Care of Heart Failure Index can be used as a unidimensional scale.
